There are few things in life better than music sung in four-part harmony. If you don't have an opportunity to sing in a school choir, find a barbershop quartet or a church group or something, because four-part harmony is just awesome.
And if you liked the song Find the Music, then Zpony has a great resource for you—a transcription of the song for four voices. Find it here and get to singing!
Thanks for sharing your talents, Zpony!
